Utilization of Poly (ethylene terephthalate) Waste and Seashell (Senilia senilis) in the Production of Roof Tiles

Abstract

Pollution has been a vital issue, especially in developing countries like Nigeria. Polyethylene terephthalate (pet) bottles from its introduction into the economy, has been a major pollutant of the environment, culminating a nuisance to the environment and unsafe habitat to human health. Water channels such as rivers and oceans are not exempted, as marine animals are also at risk of this due to the dumping of waste into our waterways. The utilization of waste pet bottles and seashell in the production of roof tiles will go a long way in the encouragement of proper disposal and management of waste. From this study, a mixture of pet bottles, river sand, and seashells in varying proportions were used to make roofing tiles. The composition with the highest strength is seen to be the P50b, which has 50% pet waste, 25% Senilia senilis, and 25% River sand. It has a smoother surface in comparison with the other compositions and more aesthetically appealing. The product showed more strength when compared with the commonly used asbestos sheets. The production of this roofing sheet will help provide affordable housing production of units, create job opportunities in both production & marketing, reduce importation of raw materials, and improve the economy of the nation.
